The height of the wall and what it is retaining and the soil it is in are
all factors in building the proper wall.
The Building Dept. here require an engineer on a wall over 48"
(that is if it is used as a foundation)
Footing/wall width and steel placement are also a factor in building these
walls.
Some Building Supplies sell stacking block and plastic pins and eposy for
"stackable wall systems" they are very useful, easy to construct.
I think the drainage is an important factor also. Allowing the water that
may build up on the other side of the wall have an escape route.

This wall was only 31" tall, and I did give it adequate footing and steel
along with drainage so that it will work out over the long haul.

The shape is curved........that is one way.......It has quite a deep
footing....
and very wide.....18" wide x 12" and more deep. I also tied it to the
concrete stairs with epoxy rebar in 3 placed and also at the garage slab.
A french drain with weep holes will provide drainage too.

Owners happy.

Is there anything anchoring that wall to prevent it from tipping
towards
the house over the years?
